Its been long time since I posted something here. Couldn't get much time for forums. But now I'm back and will try to visit my favorite forum regularly.

Someone here requested me to post the list of Google Android hidden secret codes which I found while playing with Samsung Galaxy I7500 mobile phone and posted at AskVG.com a few months back.

So in this topic, you'll get several hidden secret codes which can be used in any Google Android mobile phone to access things which are not accessible by default.

*#*#4636#*#*

This code can be used to get some interesting information about your phone and battery. It shows following 4 menus on screen:

WARNING: Never use the first option otherwise your phone camera will stop working and you'll need to take your phone to service center to reinstall camera firmware.

*#*#7594#*#*

This one is my favorite one. This code can be used to change the "End Call / Power" button action in your phone. Be default, if you long press the button, it shows a screen asking you to select any option from Silent mode, Airplane mode and Power off.

You can change this action using this code. You can enable direct power off on this button so you don't need to waste your time in selecting the option.
